**Note 1:** **CLINICAL AND PATHOLOGICAL codes** * This schema has extension codes that are defined as “PATHOLOGICAL assessment only” * PATHOLOGICAL assessment only codes (100, 150, 200, 300, 400, 500) are used when there is an orchiectomy **Note 2:** **Pure seminomas** * Pure seminomas are defined as 9061/3. (See codes 100 and 150) **Note 3:** **Lymphovascular invasion** * For codes 000, 100, 150, and 200, LVI [NAACCR # 1182] must be coded as none (code 0), not applicable (8), or unknown (9). * See the STORE or SEER manual for instructions on how to code LVI
